DnArnRIGG-ING.

Application led February 26, 1917.

To all 'whom it may concern:

Be it known that I, Gooneicn Q. Lewis, a citizen ofthe United States, residing at lVheaton, in the county of Dopage and State of Illinois, have invented a certain new and useful Improvement in Draft-Rigging, of which the following is a full, clear, concise, and exact description, referemze being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in draft riggings.

One object of the invention is to provide a draft rigging for railway ears wherein a spring gear of high capacity is eniployed in Combination with a novel twopurt. horizontal yoke detach-ably Connected with the draw bar.

Another and more 'specific object of the invention is to rovide a novel form of twopart horizontail yoke.

In the drawing forming e part of this specification, Figure 1 is a longitudinal se@ tion of a draft rlgging of a ear showing my improvements in connection therewith. Fig.- 2 is a horizontal sectional view of the strncture illustrated in Fig. 1 and taken on the line 21-2 thereof. Fig. 23 is a vertical, transverse sectional View of the structure illns trated in Fig. 1 and teken on the lino 3MB thereof. And Fig. t is a perspectivi.: view of one of the Stop castings employed with my improvements.

In said drawings, 10--10 denote channel center or draft sills of a cer underframc, to

the inner faces of which are secured the stop castings A-A. Euch of the castings A, as shown, is provided with a rca r stop l1., front. stop 12, and a central post forming front and rear limiting' stops 13 and 14 for the frontl Yand rear followers 15 and 16, re spectively, of the gear. Interposcd between the followers is a cushioning device, that shown in the drawing comprising vertical twin-arranged springs 17-17, said springs being seated aty their ends on suitable bosses 18-18 formed on the inner faces of the fol lowers and also held in spared relation hy means of a spring spacer 19. Euch of the followers has its ends movable in the recesses provided in the stop castings between the re spective main l. id limitingl stops and is further provided with on upward extension 2O and a downward extension 21 in order to form larger bearings for the springs.

connecting portion 25 and front connecting portion .Jt'. Each ot' the yoke members is also provided with n pair of side [langes QTWZT adapted to lit over thc sides 0f the draw har, said side fhrnges 7 being recessed to accommodate the, coupler-key 28, which passes therethrough and also through suitable slots in the draw har, the stop castings und thedraft sills. As clearly shown in Figs. l and 2, the side flanges of the yoke members are over-lapped when assembled with the draw bnr so that the slots therein will properly aline to receive the coupler-key. Furthermore, each of the yoke members :lll is preferably provided with a shoulder or gib 29 to engage the adjacent shoulder' on the draw' bar butt.

The upper yoke member 225 rides upon the upper flanges 30 of the stop castings and is guided thereby. In order to prevent the up per voke member from lil-ing displaced upwardly, the st op castings are preferably ro vided with oveiehnngingr tianges 31 at t ieir rear ends to thereby form short grooves or channels within whilli the rear end of the upper 4voko member is confined. The lower yoke member .221 litsl against the lower sides of the stop cnstingg's and is pro ierly supported hy means ot' the detachelble saddle plate 32, the latter having suitable horizon tal ledge portions 33 to form guide surfaces for the lower yoke rucn'iber. The saddle plato 252 also support s the` springs and followers, as will hc apparent from on inspection oF Fign 3.

Vllv moans of tho foregoing des-ribed con struction. l ani enabled to employ a two-part horizontal vvolw which may be detaehallly connected willi the drow bur and having :ill Ilu` paris so arranged lllat the gear pro'll'ior muy lio taken down without taking' out the draw bar. This is accomplishml by iirst removing tlnA Molilli plato llico taking' out the coupler-hey and dropping down the lower yoke mclnlici'. :il'lor which ilu` followers and springs can lic pulled down from between the stop motions. By the employment of the two-part horizontal yoke, l obtain direct. pulls on the rear follower which are suhstantially in line with the axis of the springs, thus minimizin :my tendency of the rear follower to ben( or buckle.

I claim:

1. In 11 draft rigging, the rombinniion with stop members, followers eoperuble therewith, cushioning menus, :i draw bur, of :1 tivo-part yoke for operatively connecting the gear proper with the drow bur, euch part of Suid yoke comprising u loop member err tending in :i horizontal plane und detuehably connected to the draw bar, :ind :i saddle plaie, the latter being adapted to support` the lower yoke part, the upper yoke pari` being supported. bj, the stop members.

:2. In n draft riggi1ig,tl1e (kombination with draft sills, of stop members secured thereto, followers eoperable with the SL03 members, rushioning means between the followers, und u draw bur, of a two-yoke arranged to oonneeb the draw bar with the followers and cushioning means, the two-party yoke including:r :in upper horizontally extendingr member. ilu suine being supported by the tops of the stop members.

Il. ln :i (I1-ufl rigging. the combination with drul't sills, of si op members Secured thereto, follmvers4 roperzible with the sto members rushioniuggmenus between the fol owers, and u druu' bur.y of :l l\\'o-pnrt yoke arranged to connor-l the druw bar with the followers und cushioning ine-uns, the two-part yoke including :in upper horizontally extending member, the sume being supported by the` tops' of the slop members, the, stop members being provi-.led with flanges over-hanging su id upper top member of the yoke to thereby prevent4 (be lutter from being displaced upwnrdly.

lu witness that l pluim the foregoing l have hereunto subscribed my nume this th (luy of Feb. 1917.
